01:07 Simple risk table recap
02:05 Numerical probabilities
04:33 Defining medical harm in severities
05:33 Simple risk matrix

I’m a medical doctor, software engineer and regulatory dude. I’m also the founder of OpenRegulatory.

Through OpenRegulatory, I’ve helped 100+ companies with their medical device compliance. While it’s also my job that we stay profitable, I try to dedicate a lot of my time towards writing free content like our articles and templates. Maybe that will make consulting unnecessary some day? :)
